Knitting track

The present innovation relates to a knitted web made of an acrylic fiber / cotton blend yarn, which can be washed ^{at 60 ° C. in a dimensionally stable and crease-proof manner.}

The nature of the goods according to the innovation is characterized by that synthetic filament threads run into the mixed yarn during knitting.

The knitted web consists of 5 to 30% by weight synthetic filament threads of 20 to 167 dtex, in particular synthetic polyamide filament threads and from 70 to 95 wt .-% mixed yarn, which in turn consists of 35 to 80 Wt .-% acrylic fibers and 65 to 20 wt .-% cotton and has a thickness of 40 Nm to 100 Nm.

The acrylic fibers in particular have a water retention capacity of less than 10% by weight, a boiling shrinkage from 0 to 6%, a cutting length of 40 to 80 mm and a thickness of 0.5 to 3.3 dtex.

The water retention capacity is based on DIN regulation 53 814 (see Melliand, Textile Reports 4, 1973, page 350). The fiber samples are

Immersed in water for 2 hours, the 0.1 wt .-% wetting agent contains. Then the fibers are centrifuged for 10 minutes.

2 yaws with an acceleration of 10,000 m / sec and the amount of water that is held in and between the fibers is determined gravimetrically. To determine the dry weight, the fibers are dried ^{at 105 ° C. to constant moisture content.} The water retention capacity (WR) in% by weight is:

^m f ~ ^m tr
WR = ———. 100

with m _f = weight of the moist fiber material with m = weight of the dry fiber material.

The processing of the acrylic fiber-cotton mixed yarn and the filament thread takes place either in the form of a Ringels, preferably each as a single thread in a row, or in a few rows as a combination enema (Filament and yarn together) or as a cladding, i.e. in each row as a combination feed.

All the usual knitting qualities for underwear can be used as knitting, preferably fine rib, single, each without or with needle pull in smooth or in catch or overhanging combination, but also interlock.

The machine division extends to all division areas for laundry, preferably from 15 to 20 units Fine rib and 24 to 28 single.

The filament threads are made of polyester or Polyamide filament threads, preferably around shiny ones Polyamide set texture.

The new fabric construction is preferably made in the color of the yarn, but the filament thread is preferred raw white. Piece coloring is possible. The dyeing must have fastness properties for 60 ° C. household laundry bring what is given with pastel colors with medium color depths.

If the fabric is knitted in the color of a yarn in tubular fabric (body size), a calender steaming treatment is sufficient with at least 12% lead, keeping the finished product 1 cm wider than the raw width, normal steam pressure and 20 m / min. Running speed for good shrinkage values from a preferably used as a basis Fabric composition 60% by weight acrylic / 10% by weight Polyamide / 30% by weight cotton.

When the goods are cut open, the usual stenter frame treatment is applied to use.

While maintaining the special softness typical of acrylic fibers, the new construction stands out when wearing the underwear due to its particularly good dimensional stability, resilience and elasticity and thus the smoothness of the fabric in clear contrast to the previous acrylic fiber / cotton linen.

I «

The new fabric construction is lighter in weight and In addition, it brings visually interesting effects compared to previous acrylic fiber / cotton laundry.

A special optical effect is achieved by using colored yarns in the color range from white to the pastel mid-tone range alternate in light and dark depth of color in each row, with in In any order, instead of the colored thread in the lighter color depth, a raw white filament thread occurs so that this thread is surrounded by the colored thread of the darker depth of color. It doesn't look raw white as a result, but optically takes up the hue of the colored yarns surrounding it (patterned plain).
